Uppercase O with dot above (Ȯ) is the Unicode character at U+022E in Latin Extended-B. Official name: LATIN CAPITAL LETTER O WITH DOT ABOVE — a capital O with a dot above, used in Livonian and some linguistic notations.
Remember
Character Ȯ
Unicode U+022E
Named entity (none)
Hex entity Ȯ
Decimal Ȯ
CSS escape \022E
Not the same ȯ · Ȱ · O
Prefer Ȯ or Ȯ in HTML markup. You can also type Ȯ in UTF-8. The lowercase pair is ȯ (U+022F). HTML5 has no named entity for either form.
Using Hex Code: Ȯ
Using HTML Code: Ȯ
Using CSS Entity: Ȯ
Typed directly: Ȯ
Case pair: Ȯ / ȯ
How It Works
1. Hex:U+022E → Ȯ in HTML. Preferred numeric form when you need an entity.
2. Decimal: same code point as 558 → Ȯ. Same glyph as hex.
3. CSS: use \022E (four hex digits) in content. Shorter forms can be misread by the CSS parser. #point::after appends that Ȯ.
4. Typed / pair: paste Ȯ in UTF-8, or show both cases with Ȯ / ȯ and lang="liv" when the context is Livonian.
5. No named entity: HTML5 does not define a name for U+022E — use numeric references or type the character. Do not confuse with Ȱ (Ȱ), which also has a macron.
Pitfalls & Tips
Common mistakes when working with U+022E.
Named
No named HTML entity
There is no named entity for U+022E. Use Ȯ or Ȯ.
vs Ȱ
Not dot + macron
Ȱ has both a dot above and a macron. Ȯ has the dot only — do not swap them.
vs O
Not plain capital O
Keyboard O is U+004F. Use U+022E only when the orthography needs the dotted form.
Encoding
Keep UTF-8 declared
Latin Extended-B letters display reliably with <meta charset="UTF-8">. Prefer numeric entities when the source file encoding is uncertain.
CSS vs HTML
Do not mix escapes
\022E belongs in CSS strings. Ȯ / Ȯ belong in HTML.
Fonts
Coverage varies
Some UI fonts omit less-common Latin Extended-B glyphs. Test Ȯ in your target fonts.
Compatibility
Browser Support
Uppercase O with dot above (U+022E) and its entity forms (Ȯ, Ȯ, CSS \\022E) are supported in all mainstream browsers. Visible glyphs depend on Latin Extended-B font coverage.
✓ Universal support

Encode with hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Unicode: uppercase O with dot above is U+022E (decimal 558) — glyph Ȯ.
HTML: no named entity — use Ȯ / Ȯ or type the character.
CSS: use \022E (four hex digits) inside content.
Meaning:Ȯ is dot only — not ȯ (lower), not Ȱ (dot+macron), not plain O.
One line:U+022E → Ȯ / Ȯ / CSS \022E (no named entity).
Frequently Asked Questions

No. Ȯ is U+022E (capital with dot above). ȯ is U+022F (lowercase). Ȱ is U+0230 (dot above and macron).
Use it for Livonian and other orthographies or linguistic text that need capital O with a dot above — not as a substitute for plain O or for Ȱ (both marks).
HTML entities (Ȯ or Ȯ) go in markup. The CSS escape \022E goes in stylesheet strings (usually content on ::before/::after). Prefer four hex digits in CSS.
